SPC tools commonly used in Six Sigma include control charts, histograms, Pareto charts, scatter plots, and fishbone diagrams.

• Control charts are used to monitor process stability over time.

• Histograms display the distribution of data.

• Pareto charts help identify the most significant factors affecting a process.

• Scatter plots show the relationship between two variables.

• Fishbone diagrams (Ishikawa or cause-and-effect diagram

FMEA stands for Failure Mode and Effects Analysis. It is used to identify and prioritize potential failures in a process or product.

• FMEA is a systematic method for analyzing potential failure modes of a process or product.

• It helps in identifying the potential effects of these failures on the system.

• FMEA prioritizes the failures based on their severity, occurrence, and detection.

• It is used to proactively address and mit...read more

Control charts are statistical tools used to monitor and control processes over time.

• Control charts display process data over time, with a central line representing the average and upper/lower control limits.

• They help identify trends, shifts, and outliers in the process performance.

• Common types of control charts include X-bar and R charts, p charts, and c charts.

• Control charts are used in quality control to ensure proc...read more

Control charts are used to monitor process variation and detect out-of-control conditions, while run charts simply display data over time.

• Control charts have control limits to determine if a process is in control or out of control.

• Run charts do not have control limits and are used to display trends over time.

• Control charts are typically used in statistical process control to monitor process stability and identify speci...read more

Non parametric tests are statistical tests that do not make assumptions about the parameters of the population distribution.

• Non parametric tests are used when the data does not meet the assumptions of parametric tests.

• They are distribution-free tests, meaning they do not require the data to be normally distributed.

• Examples of non parametric tests include Mann-Whitney U test, Wilcoxon signed-rank test, and Kruskal-Walli

Agile is a project management methodology that emphasizes flexibility, collaboration, and continuous improvement.

• Agile focuses on delivering value to customers through iterative development and frequent feedback.

• It promotes adaptive planning, evolutionary development, early delivery, and continuous improvement.

• Agile helps teams respond to changes quickly and effectively, leading to better outcomes and higher customer s...read more
